ACIf you got the phone from the same company you have service (AT&T or T-Mo) and have been with them for 90 days or more, you just call them and they will give you the code. Other options you would have to pay for include remote unlocking (gsm liberty) or codes from ebay. There is also a nokia calculator that generates codes for some models, but you would have to see if your phone is listed. A google search will get you to it.
